PURPOSE



The National Cancer Institute (NCI) through the Diagnostic Imaging

Research Branch (DIRB) of the Radiation Research Program, the National

Library of Medicine (NLM), and the Division of Stroke and Trauma,

National Institute of Neurological Disorders and Stroke (NINDS) are

seeking grant applications that will address new medical imaging

database designs that focus on non-textual paradigms.  The goal of

medical imaging databases is to provide a means for organizing a large

mass of heterogeneous, changing, pictorial, and symbolic data into a

structured environment that can be synthesized, classified, and

presented in an organized efficient manner to facilitate optimal

decision making in a health care environment.  A properly organized

imaging database can compensate for human memory limitations and

provide an environment for improved patient care, research, and

education.  Development of an effective and useful medical imaging

database must take place in an interdisciplinary environment, using the

medical knowledge from radiologists, radiation and medical oncologists,

neurologists and other specialties in collaboration with the database

research community and the imaging expertise of the computer and

Picture Archiving and Communications System (PACS) sciences.



HEALTHY PEOPLE 2000



The Public Health Service (PHS) is committed to achieving the health

promotion and disease prevention objectives of "Healthy People 2000,"

a PHS-led national activity for setting priority areas.  This program

announcement, Medical Imaging Databases, is related to the priority

area of cancer.  Potential applicants may obtain a copy of "Healthy

People 2000" (Full Report:  Stock No. 017-001-00474-0) or "Healthy

People 2000" (Summary Report:  Stock No. 017-001-00473-1) through the

Superintendent of Documents, Government Printing Office, Washington, DC

20402-9325 (telephone 202-783-3238).



ELIGIBILITY REQUIREMENTS



Applications may be submitted by foreign and domestic, for-profit and

non-profit, public and private organizations, such as universities,

colleges, hospitals, laboratories, units of State and local governments

and eligible agencies of the Federal government.  Applications from

minority individuals and women are encouraged.  Foreign institutions

are not eligible for First Independent Research Support and Transition

Awards (R29).



MECHANISM OF SUPPORT



Applications considered appropriate responses to this announcement are

the traditional research project grants (R01) and the First Independent

Research Support and Transition (FIRST) award (R29).  Although no funds

are specifically set aside for funding grants submitted in response to

this program announcement, the Radiation Research Program regards

research in this area as high priority.



Awards will be administered in accordance with PHS grants policy as

described in the PHS Grants Policy Statement, DHHS, Publication No.

(OASH) 90-50,000 revised October 1, 1990.



Because of the nature and scope of the research proposed in response to

this Program Announcement may vary, it is anticipated that the size of

an award will vary also.



RESEARCH OBJECTIVES



Background



Today, medical imaging database management and searches are largely

performed by skilled human investigators.  Although considerable

progress has been achieved in recent years in the development of new

strategies for rapid and efficient textual retrievals from text

databases, very little effort has gone into the development of

techniques for non-textual searches.  Similarly, since medical images

are poorly incorporated into the overall collection of data on cancer

patients, there is very little attempt to cohesively gather information

from images of different patients for correlation with other critical

parameters of their disease.  The wealth of information that is

potentially accessible, but not available through any currently

available technology, would contribute to new clinical knowledge about

disease progression, prognostic indicators for outcome assessment in

patients scheduled for treatment, and the ability to assess outcome in

patients who have undergone treatment.



Research Goals and Scope



Although much research has already been done in the development of

"next generation databases,"  more research is needed to address the

complex issues of developing the tools for medical imaging databases in

a clinical environment.  The research goals of this Program

Announcement include the following:



1.  Development of a descriptive language for medical images that

describes image features that define the oncologic content of images

and develops a standardized vocabulary for the geometric description of

the images;



2.  Development and implementation of advanced query languages that use

pictorial and symbolic-based object-oriented data modeling to support

complex non-textual queries;



3.  Development of new database models that incorporate the following

features:



a.  index an imaging database using image features;



b.  support spatial relations for queries that can detect change, such

as by shape and size, but are robust enough to adjust for deformations;



c.  develop object-oriented solutions that can handle levels of

uncertainty in identifying objects with fuzzy boundaries;



d.  support temporal relations that reflect both the history of the

patient, as is currently best known, as well as what was in the

database at any given point in time;



e.  allow for the development of ad hoc and customized schema that

evolve as the user gathers new data and knowledge by navigating through

or perusing the database;



f.  solve integrity problems, such as resolving a situation when two

databases contain contradictory information;



g.  carry out search and analysis processes that are both accurate and

timely and allow for the interaction of a human investigator.



5.  Development of tools that allow for the cohesive unification of

data and information from hospital information systems, radiological

information systems, image archives and imaging machines into one

system for incorporation into the electronic medical record for

incorporation into the electronic medical record.



Research and implementations of database systems must proceed in

interdisciplinary environments that successfully combine the expertise

and knowledge from the medical community with that of the database and

computer science disciplines.



APPLICATION PROCEDURES



The research grant application form PHS 398 (rev. 9/91) is to be used

in applying for this program announcement and will be accepted at the

standard application deadlines as indicated in the application kit.

These forms are available at most institutional offices of sponsored

research and from the Office of Grants Information, Division of

Research Grants, National Institutes of Health, Westwood Building, Room

449, 5333 Westbard Avenue, Bethesda, MD 20892, telephone

(301-435-0714).



The PA number and title must be typed on line 2a of the face page of

the application form.  The completed original application and five
